(A) any differences in the frequency or geographic span of the two brands’ advertising This explains brand familiarity, but does not explain the choice of the participants under time pressure

(B) how much participants enjoyed or valued the activities most commonly associated with the products Enjoyment in the activity doesn't help determine the reason for choice.

(C) the degree of importance ascribed to the product by the researchers in their instructions to the participants This is applicable to both the products

(D) the nature of the events or situations causing stress in the participants’ lives outside of the experiment Already given all stress are equal

(E) the number of factors that participants thought necessary to consider in judging the unfamiliar product relative to the familiar one Correct. The participants might have thought they need to consider a lot of factors and hence went along the familiar product to save time.

Soundness of the conclusion : the sight of well known product countered the extra stress of being rushed to the main group, cannot be assesed without taking into account :

A. Differences in ads will not affect. Eliminate.
B. Participant's enjoyment related to the products is not not relevant. Eliminate.
C. Importance of something is not necessarily the reason of product countered the stress of being rushed. Eliminate.
D. Cause of the stress is not necessary to evaluate the conclusion. Eliminate.

Leaves us with E.
E. If less factors used to asses unfamiliar product then maybe fewer factors thought to be necessary are to be considered while choosing a familiar product.

Ans is E.

In a research study, participants were asked to choose between two brands of a certain type of product: one familiar, one unfamiliar, and report their choice to the researchers. Before making the choice, one group was told emphatically to hurry, as the researchers were behind schedule and pressed for time; the other group was told that the project was ahead of schedule, giving them ample time to make the decision. Every participant in the former group, but only about two-thirds of the latter group, chose the familiar brand. Since the participants self-reported equal amounts of stress in their current lives, the researchers concluded that the sight of a well-known product countered the extra stress of being rushed for the first group. The soundness of this conclusion, however, cannot be assessed without taking into account _________.

Which of the following most logically completes the argument above?

(A) any differences in the frequency or geographic span of the two brands’ advertising

(B) how much participants enjoyed or valued the activities most commonly associated with the products

(C) the degree of importance ascribed to the product by the researchers in their instructions to the participants

(D) the nature of the events or situations causing stress in the participants’ lives outside of the experiment

(E) the number of factors that participants thought necessary to consider in judging the unfamiliar product relative to the familiar one

based on passage, the people who were rushed chose familiar product while those who had time decided properly.
option a - nothing related to advertising is mentioned
option b - its about reduced stress while going for familiar products in less time. not relevant
option c - not the main reason as nothing mentioned about instructions in the passage option d - irrelevant
option e - this is correct as stress is not the only factor but participants with less time considered less factors while choosing

The question talks about an experiment wherein participants choose between familiar and unfamiliar brand - Group 1 was told to select the brand in less time and group 2 in more time

Option A - This does not lead to discussion related to the conclusion and hence is not correct
Option B - This is also not relevant for arriving at conclusion and hence is not correct
Option C - The degree of importance does not point towards the conclusion and hence is false
Option D - The nature of events or situations causing stress - This is indirectly related and hence not correct
Option E - This seems to be the incomplete conclusion since there might be other factors impacting the result and hence this is the correct answer.

Correct Answer - Option E

A. Difference in advertising not important. They already have a familiar and unfamiliar brand for the survey.

B. Enjoyment of the activities associated with product is irrelavent.

C. Do not matter if the product is important or not. This doesnt explain difference between the groups.

D. They participants have already been assign to groups with equal levels of life stress.

E. BEST ANSWER. If you were assessing the product on 100 different factors that you had to consider and you were rushed for time you would just take the simple route and pick the product you are familiar with. If you had only one factor to consider and were rushed for time you might still figure you have time to make a good assessment and would not get too stress and make a full assessment of the products.

A. If one brand was advertised a lot more than the brand that could be why people liked the brand more.. This does not really help us figure out if being in a hurry made people choose the brand they know. Both groups saw the brands, the familiar brand and the other brand.

B. This is asking if people liked the things they did with the product. That might change what people like overall. It does not explain why the people who were in a hurry chose the familiar brand more often than the other people.

C. If the researchers made the product seem important to people people might have acted differently.. This still does not answer the main question of why being in a hurry made people choose the familiar brand more.

D. The researchers already said that both groups had stress in their lives. Knowing what caused that stress does not help much with the conclusion about the brand.

E. This is correct. If the unfamiliar brand required people to think about a lot of things before they could decide then people who were in a hurry might just avoid thinking that much and pick the brand instead. In this case the result would not show that familiar brands make people less stressed. It would just show that people who are, in a hurry make the choice they choose the familiar brand because it is easier.

I think the answer is E.

A. INCORRECT >The way we showed the advertisements could have affected how well people knew the brands. Since everyone saw the same brands it does not explain why the group that was in a hurry got the result they did.

B. INCORRECT > Whether or not people liked the product is not the reason why being in a hurry changed their decision.

C. INCORRECT > The instructions about which brand was important did not matter because we did not specify a brand. This does not explain why people chose a brand they were familiar with.

D. INCORRECT > We asked everyone about stress in their life and it was the same for everyone so it did not make a difference in how stressed people were. Therefore it is not important.

E. CORRECT > If deciding on a product required more thinking then it can be assumed that people who were in a hurry wanted to avoid the difficulty of making a complicated decision and chose a brand they knew instead. So it might be an issue of not wanting to deal with something rather than trying to reduce stress. The decision process, for products involves more cognitive thinking and hurry participants might want to avoid this complexity, which is why they choose a familiar brand like the brand they know because it is easier.

Correct answer is E.

Researchers conclude that the rushed participants chose the familiar brand because familiarity reduces extra stress caused by being hurried.

but it could be said that when people are rushed they choose something they know and brands come into that as evaluating something they know requires less effort.

To pick the right answer we need to know whether participants believed the unfamiliar producet required consideration of more factors than the familiar product

A - irrelevant doesn't mention anything about geography
B - again irrelevant, the products are similar/identical but the brands vary
C addition to the experiment irrelevant, would apply to both
D - this is tempting, but incorrect, the specific cause of participants outside stree do not explain why being rushed cased everyone to choose the familiar brand.
E to differentiate between we need to know whether participants believe the unfamiliar product required consideration of more factors than the familiar product - keep

The answer is E because the researcher rushed the participants, prompting them to choose, which is familiar in nature. Therefore, there is little to no evidence that the participants had enough opportunties to explore both the products. As the time was very short, they did not have the time to judge the unfamiliar products. It is the answer.

(A) What is the point of geographical advertisement here? It is not telling us any information whether there are any factors that help products observe by the participants. Eliminate.
(B) The question does not ask about whether the participants enjoyed or not. In fact, the test is about whether participants explore the factors as they are being rushed to make decisions.
(C) The researcher did not tell any importance about any of the choices. Irrelevant. Eliminate.
(D) We do not know whether this test has any impact outside of their lives. Out of scope. Eliminate.

Answer is E.

The statement that most logically completes is the statement E.
Option A, B and C are highly irrelevant.
Option D also talks about external events causing stress instead of focusing on the factors that might be considered by participants in making the choice

Let's breakdown the argument:
There's an experiment run by reseachers.
The participants have to choose between a familiar brand and an unfamiliar brand of a certain type of product.
One group of participants were rushed into decision making by putting them under time pressure. Whereas the other group was told that they had ample amount of time to make the decision.
The first group ended up chosing the familiar brand. 2/3 of the other group chose familiar brand while the remaining chose unfamiliar.

Important to note that participants reported equal amount of stress - participants of both the groups.
So the researchers concluded that, the extra stress of being rushed to choose between the familiar and unfamiliar brand was countered by the familiarity of the brand they knew - well known product.

We need to figure out something that the researchers have not taken into consideration while arriving at their conclusion.

A - It really doesn't affect because one brand is familiar and both sets of the participants knew about the familiar brand so their advertising plays no role in figuring out whether the conclusion make sense - Incorrect

B - This statement focuses on the activity associated with the product than the brand of the product - irrelevant

C - Whether the product is important or not does not matter and neither the passage indicates that the researchers communicated differing importance of the product itself. - irrelevant

D - This relates to the stress outside of the activity altogether. - irrelevant

E - The number of factors that the participants considered for a non-brand to brand product may affect their decision making. They were stressed at equal levels before the choice. Time pressure would simplify the decision making by simply reducing the number of factors that the participants will judge the familiar brand vs the unfamiliar brand on. The participants may have found it easy, under time pressure, to select a familiar brand because they simply don't have to think much not because the familiarity to the brand relieved some extra pressure. - This is an alternative to the explanation of the reseachers - Correct.

Researcher mentions being stressed -> lead to chose familiar option
Other way to look at it could be -
Being stressed group had less time & so considered less factors to evaluate
While the other group had not rush & so considred many factors to evaluate
So Option E

The researchers leap from a beavior (rushed people all picked the familiar brand) to an emotional cause (the familiar sight soother their stress) - simpler explanation is that sizing up an unknown brand takes time and effort. If the comparison demands weighting six facotrs and the one familiar one demands zero, the busy people default to it on the basis of time cost alone.

my prethinking- conclusion says familiar brand reduces stress. we need to look for alternative explanation
familiar brand needs less evaluation
unfamilar brand requires more factor to consider
under time pressure , choosing the familiar brand may be easier, not stress- reducing

A-advertising is irrelevent
B- product preference irrelevent
C-same inst to both side
D- already given in the passage
E- correct ans

The researchers found that:
- The group that was rushed all chose the familiar brand.
- Only about two-thirds of the group that was not rushed chose the familiar brand.
- Since both groups reported similar overall stress in their lives, the researchers concluded that seeing a familiar brand helped counter the extra stress of being rushed.

To evaluate this conclusion we need to know whether the difference in choices was really due to stress or something else.

(A) This asks about differences in advertising between the two brands. If one brand was advertised more both groups would be affected equally so this doesn't explain why the rushed group behaved differently. We can eliminate A

(B) asks whether participants enjoyed or valued the activities associated with the products. This may affect which product they like but it doesn't explain why being rushed changed their choices. Eliminate B

(C) asks whether the researchers made the product seem more or less important in their instructions. If the rushed group was also led to believe the decision was unimportant (or very important) that could influence their choice independently of stress. This could provide an alternative explanation so it is relevant.

(D) asks about the causes of stress in participants' personal lives. The researchers already told us both groups reported equal amounts of life stress. The source of that stress is not important because the conclusion is about the stress created during the experiment.

(E) is the correct answer because it asks whether choosing the unfamiliar brand required participants to consider more information than choosing the familiar brand. If the unfamiliar brand requires more thinking, then rushed participants might simply choose the familiar brand to save time, not because the familiar brand reduced their stress. Without considering this possibility we cannot properly assess the researchers' conclusion.

participants were asked to choose between familiar product and unfamiliar product.
one group was told to hurry as they were behind the schedule and other group was told to take enough time as they were ahead of the schedule.
all the participants in former group chose familiar product and 66% of people from latter group chose familiar product.
moreover, participants reported equal amount of stress in their current lives, researchers concluded that sight of well known product countered extra stress of being rushed for first group.

but conclusion cant be assessed without taking into account. ----

A not concerned with geographic span of advertising. completely irrelevant. out.
B it could have been for the either of product. not enough to counter. out.
C importance of product would have created more stress so this is not helping at all. out.
D its not important to know nature of outside stress. this doesnt know provide any reasoning that counters the researchers conclusion. out.
E yes, if there were too many factors to consider and participants already had stress so they just went with the known product to avoid any more stress. but there were not many factors then researchers conclusion could come under scanner. keep.

Every participant in the former group, but only about two-thirds of the latter group, chose the familiar brand. Since the participants self-reported equal amounts of stress in their current lives, the researchers concluded that the sight of a well-known product countered the extra stress of being rushed for the first group. The soundness of this conclusion, however, cannot be assessed without taking into account _________.

Which of the following most logically completes the argument above?

(A) any differences in the frequency or geographic span of the two brands’ advertising

(B) how much participants enjoyed or valued the activities most commonly associated with the products

(C) the degree of importance ascribed to the product by the researchers in their instructions to the participants

(D) the nature of the events or situations causing stress in the participants’ lives outside of the experiment

(E) the number of factors that participants thought necessary to consider in judging the unfamiliar product relative to the familiar one

To logically complete the arguement, we need to find information which can suggest whether any other factors have been considered whilw evaluating the familiar & unfamiliar product. In that case the reasoning behind decision making under time constraint or in sufficinet time can be explained.

A - It explains the familiarity, not teh reason behind the choosing/not choosing the unfamiliar product.
B - it talks about preference, not about the effect of time constraint.
C - Importance is irrelevent to familiarity & factors considered under time constraint.
D - Cause of stress is irrelevent. And amount of stresss were alreday reported & assessed & reported in the study.
E - it explains the reasoning about teh additional factors that were considered in the availibility of time. That is in line with what we are looking for.

Answer : E

A and B are irrelevant as they introduce a new concept. C,D are supportive but not directly gives a way to categorize the result. So E is the right answer

A-incorrect: here both groups were choosing between the exact same two brands under identical baseline conditions, so any pre-existing brand popularity affects both groups equally.
B-incorrect: Enjoyment associated with activities would affect both groups equally as participants were random, but it does not explain the difference in behavior under time pressure.
C-incorrect: here there is no indication that the researchers ascribed any specific importance to the products in their instructions, they only gave instructions regarding the time.
D-incorrect: the researchers already established that both groups self-reported equal amounts of overall life stress, the nature of the external stress is not relevant.
E-correct- this shares an alternative explanation for results that shows rushed participants may have preferred the familiar brand because it was cognitively simpler to choose and not because it reduced stress.
